Welcome to the Friends of Stocker's Lake Website

This website is owned and maintained by Friends of Stocker’s Lake (FoSL), a registered charity. FoSL exists to :

  1. - conserve, safeguard and enhance Stocker's Lake as a Local Nature Reserve
  2. - help and extend the scope of the work of the warden at Stocker's Lake
  3. - foster public support for and appreciation of Stocker's Lake as a local nature reserve.

Stocker's Lake, near Rickmansworth just inside the M25, is bordered on one side by the river Colne and on the other by the Grand Union canal. It is a place of great beauty and it supports a huge variety of wildlife, especially birds, particularly winter wildfowl. It is owned by Affinity Water and managed by Herts & Middlesex Wildlife Trust, actively supported by local people who are the Friends of Stocker’s Lake.

Within this website you will find details of organised walks and other events on the reserve, news of interesting recent sightings of birds, details of how to join FoSL for a mere £5 per year, and much more.

FoSL site attracts US interest!

This week we received an email from Jessica Lowe, a middle school science and health teacher at a private school in Colorado, USA. Her class is working on a project that aims to get them outdoors identifying wildlife and learning about what's in their gardens and surrounding areas. As part of this some of her students came across the FoSL website and Jessica emailed to let us know!

The FoSL committee recently reviewed FoSL's main operational risks and insurance arrangements. This has led to £5,000,000 of public liability insurance cover being put in place.
